ABSTRACT:
A radio frequency control technique for use in a wideband communications system, such as a Code Division Multiple Access (CDMA) system in which the use of several wideband forward channels is allocated in each cell depending upon the apparent location of the mobile station in the cell. In particular, a first set of forward channel frequencies is reserved for the mobiles located within a first certain radius of the base station antenna, and a second set of channels serve the area forming mobiles located in a concentric annular ring centered around the base station antenna. Third, fourth, and subsequent concentric rings may be used to provide successively longer radii from the base station to support the use of additional frequency sets in each cell.
